Constant hissing and buzzing

[imboringlycool]

Hello all,

So I bought a new computer recently. I have 2 yamaha studio monitors hooked up to its 3.5mm port. Previously they were hooked up to my laptop. Occasionally they would crackle alittle bit and then stop, or I would wiggle the chord a bit and it would stop. When I have my headphones plugged into the computer, it sounds fine.

So the problem I am having now, is that there is a cooonstant high pitched hiss/and fuzz coming from the speakers, the left one in particular. And oddly enough, when I use mouse wheel to scrol up and down, it buzzes when I do that. This has been driving me nuts and makes me not want to use the computer, If anyone could offer a solution, I would be most grateful!

Sounds to me that the audio port isn't grounded properly so you are picking up interference from other components in the computer. Unless there is another 3.5mm port on the computer then you are pretty much stuck with the hissing unless you can find another interface.

This is the back of my computer.. See any alternatives? Also, any way to ground it?

Yup EMI, and if it reaches video cable prepare for ghosting

Looks like thats your only port. No way to ground it that I know of since it has to do with the built in audio components not having a good ground to the motherboard. Higher quality motherboards tend not to have this problem. A good work around I came up with when dealing with budget oriented motherboards was to use a USB soundcard.
